.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT...AN UPPER LEVEL TROUGH
WILL CONTINUE TO MOVE ACROSS THE AREA THROUGH THIS EVENING AND THEN
OUT OF THE AREA OVERNIGHT. COLDER AIR WITH THIS TROUGH HAS DEVELOPED
MILDLY UNSTABLE CONDITIONS AND THERE ARE NUMEROUS CONVECTIVE SHOWERS
AT THIS TIME. THIS WILL CONTINUE THIS EVENING AND SLOWLY TAPER OFF
OVERNIGHT. SNOW LEVELS HAVE BEEN AROUND 4000 FEET AND HAVE RECEIVED
REPORTS OF A COUPLE OF INCHES OF SNOW AT LA PINE. EXPECT THAT THE
MOUNTAINS WILL ALSO RECEIVE UP TO A COUPLE OF INCHES OF SNOW
TONIGHT. THERE HAVE ALSO BEEN A FEW LIGHTNING STRIKES IN THE
COLUMBIA GORGE. EXPECT THAT LIGHTNING ACTIVITY WILL END IN THE NEXT
FEW HOURS WITH SUNDOWN. THE BIG ISSUE IS THE WIND WHICH REMAINS JUST
BELOW WIND ADVISORY LEVELS EXCEPT FOR BRIEFLY IN A FEW LOCATIONS.
HAVE HELD OFF ON ISSUING ANY WIND ADVISORIES, BUT WOULD NOT BE
SURPRISED IF ONE GETS ISSUED LATER FOR NORTH CENTRAL OREGON OR THE
BLUE MOUNTAIN FOOTHILLS. WITH COLDER AIR OVER THE AREA TONIGHT
TEMPERATURES WILL BE A FEW DEGREES COOLER THAN LAST NIGHT.

ANOTHER PACIFIC WEATHER SYSTEM WILL MOVE THROUGH THE AREA FRIDAY
AFTERNOON AND EVENING WITH ANOTHER CHANCE OF RAIN AND MOUNTAIN SNOW.
SNOW LEVELS WILL BE AROUND 3500 FEET IN THE MORNING THEN RISE TO
4500 FEET IN THE AFTERNOON GIVING THE MOUNTAINS UP TO A COUPLE
INCHES OF SNOW. WINDS WILL PICK UP AGAIN IN THE AFTERNOON BUT WILL
NOT BE QUITE AS STRONG AS TODAY, MAINLY 15 TO 30 MPH WITH GUSTS TO
40 MPH. TEMPERATURES WILL BE A COUPLE OF DEGREES WARMER THAN TODAY.
THIS SYSTEM WILL MOVE OUT OF THE AREA OVERNIGHT AND A RIDGE WILL
MOVE OVER THE AREA WITH DRY WEATHER AND LIGHT WINDS EXPECTED
SATURDAY AND SATURDAY NIGHT. CLEARING SKIES WILL LEAD TO
TEMPERATURES BEING A FEW DEGREES WARMER SATURDAY AND SEVERAL DEGREES
COOLER SATURDAY NIGHT. PERRY

.LONG TERM...SUNDAY THROUGH THURSDAY...A FAST MOVING COLD FRONT WILL
SWEEP ACROSS THE REGION LATE SUNDAY BRINGING A CHANCE OF
PRECIPITATION. THIS WILL BE FOLLOWED BY A BUILDING RIDGE OF HIGH
PRESSURE OVER THE PACIFIC NORTHWEST THROUGH THURSDAY. ONE WEAK
SYSTEM WILL TRY AND MOVE THROUGH THE RIDGE ON WEDNESDAY BUT MAINLY
BRING SOME CLOUDS AND A VERY LOW CHANCE OF PRECIPITATION. THE HIGH
PRESSURE WILL ALLOW FOR TEMPERATURES TO BE A LITTLE ABOVE NORMAL.

&&

.AVIATION...00Z TAFS...AN UPPER LEVEL TROUGH WILL CONTINUE IMPACTING
THE AREA THROUGH THIS EVENING WITH SOME SHOWERS AND WINDY CONDITIONS
OF 20-30 KTS AND HIGHER GUSTS. SOME MVFR CONDITIONS WILL BE POSSIBLE
DUE TO LOW CEILINGS IN VICINITY OF SHOWERS THROUGH THIS EVENING.
WINDS WILL DECREASE OVERNIGHT SLIGHTLY AND SHOWERS ENDING FOR A
RETURN TO ALL VFR CONDITIONS UNTIL THE NEXT WEATHER SYSTEM ARRIVES
FRIDAY WITH SOME MORE SHOWERS AND BREEZY CONDITIONS.
